Hermine continues to be a very strong system off the Virginia coast on Sunday with winds near 70 mph. WYFF News 4 Meteorologist Chris Justus said the system is no longer tropical in nature but is just as strong as hurricane. Chris said it’s no longer a tropical system because the center now has a “cold core” versus a “warm core” which is needed for the tropical designation.

Since the impacts will be the same as a tropical system, the National Hurricane Center has extended the tropical storm warning northward from Delaware, New Jersey up through Connecticut, including New York City.

Chris said Hermine is expected to strengthen even more as it moves north just offshore of the New England coast. Storm surge will be a big concern from the Jersey Shore up through New York City as water could rise 3-5 feet in some locations.

Rip currents will be very dangerous along the eastern seaboard from Florida all the way up to Maine with Hermine just off shore.

The storm moved from Georgia into South Carolina about 2:30 p.m. Friday, bringing heavy rain and tropical storm force wind gusts of up to 55 mph.

South Carolina officials said Hermine spawned scattered reports of flooded roads, downed trees and power outages but no major damage.Emergency Management Division spokesman Derrec Becker likened it more to a bad summer storm than a hurricane.

In the Charleston area, only a few roads were closed because of flooding, not uncommon during summer thunderstorms.

The storm will move offshore of the North Carolina coast on Saturday. The forecast has the system remaining strong, though losing tropical characteristic, and remaining close to the northeast coastline of the U.S. through the middle of next week.

Hermine will sit off the New England coast, where storm surges could get very high along the coast of New York and the Jersey shore. Strengthening is forecast once the center of Hermine moves offshore Saturday afternoon.
